NAME

nauty-geng - generate small graphs  

SYNOPSIS

geng [,-cCmtfkbd#D#/] [,-uygsnh/] [,-lvq/] [,-x#X#/] ,n /[,mine/[,:maxe/]] [,res/mod/] [,file/]  

DESCRIPTION

Generate all graphs of a specified class.
n
: the number of vertices
mine:maxe : a range for the number of edges
#:0 means '# or more' except in the case 0:0
res/mod : only generate subset res out of subsets 0..mod-1
-c
: only write connected graphs
-C
: only write biconnected graphs
-t
: only generate triangle-free graphs
-f
: only generate 4-cycle-free graphs
-k
: only generate K4-free graphs
-T
: only generate chordal graphs
-S
: only generate split graphs
-P
: only generate perfect graphs
-F
: only generate claw-free graphs
-b
: only generate bipartite graphs
(-t, -f and -b can be used in any combination)
-m
: save memory at the expense of time (only makes a
difference in the absence of -b, -t, -f and n <= 28).
-d#
: a lower bound for the minimum degree
-D#
: an upper bound for the maximum degree
-v
: display counts by number of edges
-l
: canonically label output graphs
-u
: do not output any graphs, just generate and count them
-g
: use graph6 output (default)
-s
: use sparse6 output
-h
: for graph6 or sparse6 format, write a header too
-q
: suppress auxiliary output (except from -v)
See program text for much more information.
